摘要：The invention relates to a method for the continuous synthesis of monoalkyl-

hydrazines with a functionalised alkyl group. The inventive method is characterised in thatit comprises a step consisting in demixing a solution containing the synthesised

monoalkyl hydrazine, by reacting an anhydrous amine with monochloramine, in an organicphase and an aqueous phase with the addition of anhydrous sodium hydroxide. Theinvention can he used to obtain perfect selectivity in relation to monoalkyl-hydrazinewithout the presence of the di- and tri-substituted forms thereof. According to theinvention, the starting amine which has not reacted is collected and reused directlywithout any additional treatment.
